FLYING-MACHINE.

No. 867,525. Specification of Application filed December 21, 1906'. I fierial No. 348,991.

To all whom it may concerns l I Be it known that I, ANTHONY OBRA'rE, a citizen of Garfield and Territory of Oklahoma, have invented Improvements in aFlying-Machine, of which the following is a specification, reference being had therein to the'accompanying drawings.

My invention relates to .certain new and useful improvements in flying machine, and the objects of my invention are to improve the means for maintaining the equilibrium of the machine, means for guiding and turning the machine, means for driving the machine and other details, as will be hereinafter pointed out.

With these objects in view 'my invention consists in certain constructions, combinations and arrangements of parts, the preferred form of which will be first described in connection with the accompanying drawings,-and then the invention particularly pointed. out in. the appended claims.

Referring to the drawings wherein I show one em bodiment of my invention and wherein the same part is designated by the same reference numeral wherever it occurs, Figure '1 is a perspective view of a flying form of my invention; Fig. 2 is a view of the forward section of the machine looking from the rear; Fig. 3 is a top plan View showing the aeroplanes in dotted lines; Fig.4 is a detail view showing the arrangement of the fQrWard'rudder; Fig. 5 is a detail perspective view of the connection between the bars of the main frames of the aeroplanes; Fig. 6 is a side elevation of one of of'parts of the propeller; Fig. 8 is a detail view of a pair of connected blades of the propeller; Fig. 9 is a view similar to Fig. 2, showing however .a'modified construction; Fig. 10 is a detail view showing apor tion of the connection illustrated in Fig. 9 enlarged l 1 designate a pair of rods to which are secured the aeroplanes 2, and 3, '3 are balloon: sections, secured between the aeroplanes in themanner fully described in my allowed application No. 302,821, filed February. 24, 1906. v 4 designates a series oi triangular braces connected together at their bases by means of thebars 5, 5, the triangular braces and forming two frames,

one for the forward aeroplane, and one for the after, The bars 5'at their inner end are 'connected'together by means of the shaft 6 passing throughey'esfi formed in'the adjacent ends of the bars5. -Ait-the ."third' angle of the triangle braces 4am provided b'earings 8, in which are loosely. mem s l, s 1.ippor"ting the aeroplanes;

Letters Patent. 7 Patented dot. 1 1907.

The adjacent ends of the rods 1 are connected together by means of the connection shown in the detail in Fig. 5, this connection consisting of a pair of arms 9 pivoted at 10 to one of the rods 1, and extending out on each side thereof, and a second pair of arms 11 pivoted at'l2'to the other rod, and extending out- 'wardly therefrom, the free ends of the arms of the opposite rods being secured together by means oi'the connecting links 13 in which they are pivoted by means ofthe pivots 14.

.16 designates a car .in which the power mechanism is mountedandwhich carries theoperator. This car is provided with a forward pairgof wheels 17 and an after pair of wheels 18, the after wheels being preferably' carried by arms 19 to which is provided a lever 20, whereby theymay be raised and" lowered in relation to the car to give the machine the desired inclination, as fully described iii my application referred to. The car is supported from the shaft 6 by a pair of rods 21 secured to about the central section of the car. These rods or hangers loosely engage the shaft 6, which construction isalso fullydescribed in my'aforesaid appli-, cation j 22 designates a pulley mounted in the car to which power is applied from any suitable source, not shown. 23 is a belt-running from the pulley 22 to pulley 24, mounted. upon the. shaft 6, whereby the shaft is rotated.- 25 designates a second belt runningfrom the pulley 22 to the pulley 26, from which isdriven thepropeller 27 constructed as fully shown and described in my above mentioned application. I

28 designates a cord secured at each end to the links 13 and running around awheel 29 mounted on a cross brace 30 extending between the supporting links 21.

. By this construction the aeroplane-roan be tilted in 'relation to the car toward the right or toward the left, and whereby the machine is steered.

31- designatesa cord extending freinone of the triangular braces 4 of the fQI'WBId SGCtiOHQtO a wheel 32, and 33 designates a similar cord extending from one of the. triangular braces 4 of the after sectionof the frame to a wheel 34. Bythese cords'the aeroplanes can be set at an angle to eachother'for the purpose fully de? scribed in my applicationabove referred 'to.

36 extending upwardly fromthe' rear of the car, and 37 by ;the positionof the plane may be'adjnsted for the 35 is a balancing' plane,pivotally connected to arms purpose fully described in my ahovereferrd to ap plication. Z l v I 40 designates a pair of propellers mounted on'the 5 42. 43 are a pair ofrims secured to tho vsh'aft 6 by spokes A4. 45 are shafts rotatably mounted in the rims.40 and the ri ngs 43. These shafts are arranged in pairs around the rims as shown in Figs. 6 and 8. 46 are rectangular blade sections secured to the shafts 45,

the blade sect-ions being secured to the shafts at oneside of their central line, as indicated in Figs. 6 and 8 These sections are connected together by links 47 pivoted at 48 to the sections, whereby the sections move in-nnison. At thev lower end of each shaft 451 provide a 'cam engaging arm 49, in the outer extremities of which are antifriction rolls 50, these rolls being adapted to contact with a cam section 51, formed upon the outer bearings 52 of the shaft 6-, said bearings being supported by the braces 53 extending from the supports 21.

From the above described construction it will be seen that the cams are held stationary while the shaft I carrying the propellers rotates, and that while the propollers are in the position in which the arms 49 engage 2 5 the cams, they will be held at right angles tothe direction of rotation of the propeller, as indicated in Fig. 6

while during the remainder of the-rotation they will be free and can turn and feather, due to the fact that the blades are not centrally mounted on the shaft, and

consequently there is a greater pressure on one side of the shaft than on the other.

It will be understood that in the present form of my invention the steering of the machine is accomplished by tilting the aeroplane'to one side in relation to the car, which is effected by means of the wheel 29. Tilting the aeroplane to the right causes the machine to veer to the right, and tilting it to theleft causes the machine to turn-to the left. In order t5 assist in thus steering the machine I provide a forward l aeroplane 54 which is carried by ashaft 55 mounted in a bearing 56 carried by supporting braces 57, ex-' tending down from "the forward portion of the forward section of the rame. .-"lhis aeroplane, as will be seen is mounted at an angle to the plane of'the main.aero- '1 plane section 2. 58 designates a" pair of armseirtending out on opposite sides from the shaft 55, and

designates a pair of arms extending outfrom opposite sides of the rod 1. 60 ,are cordsconnecting the ends "of the arms 59 to the ends of the arms 58.- From this "construc'tion it will be seen that when the main aeroplanes'are tilted the aeroplane 54 will be correspondingly tilted, which willgive increased turning power to the machine: 61 designates a rudder mourned on the shaft 62 at the stern of the machine, the-shaft 62 being mountedin a bearing 63 supported by braces 64f at the stern of the after section of the frame. At its upper portion the shaft 63 is provided with an arm 65 having a slot 66 therein" and 67- is a rod fast to the rodl which extends down and enters the slot 66.

From this construction it will be seen that the rudder will be turned upon the tilting of the aeroplane in a direction to assist in the turning movement.

said aeroplanes will all tilt Referring to Fig. 9, I have shown a construction whereby the equilibrium of the machine is automatically controlled. In this construction, a pair of arms '68 extend out from opposite sides of the shaft 1. By

means of cords 69 the extremities of these arms are connected to the extremities of a bar 70 from which egctends a stub shaft 71 having fast thereon a corrugated or milled collar 72. 73 designates a pair of arms pivoted at 74 to the bar 70. These arms 73 having their portion 75 above the bar 70 connected by a spring 76, and they also have the portions 77 extending on opposite sides of the roughened collar 72, the inner faces of these ektensions being roughened to engage with the collar. To the extremities of thearm 73 I secure, by cords 78, a weight 79. By, this connection it will be seen that when the machine tilts in one direction it will cause weight to swing toward the lower side, which will cause the arm 73 on the opposite side to move downward, turning the corrugated collar 72 which, through the arm 70, will tend to ,return the aeroplane sections to normalposition. The corrugated collar and arm 73 are for the purpose of adjusting the relation between the arms carrying the weight and the aeroplanes, whereby the position of the aeroplanes, when the weight is immediately below the shaft, can be varied. The construction described also permits the arms being raised from the shaft by merely raising the "weight, should it be desired to take the machine out from under the control of this automatic means.

' From the above description it is believed that the operationof my machine will'be apparent without further description.

.While .Ihave described what I believe to be the preferred form of my invention, I desire to have it understood that many changes may be made in the form, construction and arrangement of partswithout departing from the spirit of my invention.

What I claim as new and desire to secure by Letters Patent is 1. In a flying machine the combination with a frame havln'gja shaft journaled therein, of a pair ofaeroplanes secured to the shaft in fixed relation to each other, an aeroplane extending outwardly from each side of said shaft, a car supported from said frame and connections controlled from the car, whereby said aeroplanes may be tilted to steer said machine laterally.
